I just placed my order for the M2 kit yesterday and noticed that the online kit instructions haven't been updated in over a year. It appeared to me by reading on the forum here that the kit is even easier to assemble since then...is this true? Are there some areas of the old instructions that are now out of date then? Does the kit come with an updated doc?

I got my kit last week and the instructions were clear enough for me to follow. I recommend going through both the building instructions and the electronics installation manuals before doing anything, this way you will know what to expect. The most confusing part for me was figuring out where everything plugs into the rambo, just do it slowly and triple check that everything is plugged in correctly. Took me about 7 hours to build and my first print came out perfectly. Been printing everyday without any real issues.
